Am I Using UEFI

[bookie32]

Hi guys!

I have tried to see by convential methord like msinfo32....nothing about legacy or UEFI there...

I have tried looking ofor the setupact.log to see if I am actually using UEFI...no log file.....ccleaner can be the culprit....lol

What other ways can I use to see if I am actually using UEFI mode?

Find bootmgr in root of your boot (or system or both) volume.

Delete it.

Reboot.

If it doesn't boot, it is BIOS, if it boots again it is UEFI. 

Now, seriously.

Have a look at your system volume (or boot volume or both), that may be either your C:\ volume or in case of GPT the "hidden" one.

Unless it is a FrankenInstall, you will have EITHER :

\bootmgr
\boot\BCD

OR:

\EFI\Microsoft\Boot\bootmgfw.efi or \EFI\Microsoft\Boot\bootmgr.efi
\EFI\Microsoft\Boot\BCD

And/or run BCDEDIT as follows:

bcdedit.exe /enum ALL

There's also this blog post, look under Differences between UEFI vs. Legacy BIOS boot install.

Must have been added starting with Windows 8.

Yes....I think you are right...

You can also try this: How to Check if Your Computer Uses UEFI or BIOS

I tried this on Windows 7 SP1 x64 and looking in System Information there wasn't a "BIOS" entry. However, I did find the setupact.log file in the folder C:\Windows\Panther and there using the search phrase Detected boot environment was the information (in my case "BIOS"). The guide I point to says this second method is for Windows 10, but works for Win7 on my system.

Yes....but I haven't the setupact.log...think it might have been removed by ccleaner....;)

Thanks anyway

im sure you can open cmd in admin and type diskpart , then list disk , GPT = UEFI , MBR = legacy , if gpt doesnt show a star it means its in legacy basically

I'll try contacting Misty, maybe he simply forgot to renew the domain.

Anyway, in the meantime you can use and peruse the Wayback Machine:

@burd

JFYI:
MBR=BIOS

and:

GPT=UEFI

are not perfect equivalences.
